Comparison of INR measurements before and after NMV/r therapy. (A) Comparison of pre-NMV/r INR values with those measured during NMV/r therapy (n = 13) or between days 5 and 14 (n = 27, Wilcoxon signed-rank test, ∗P = .026). (B) Pre-NMV/r INR values compared with the lowest or highest INR measured between days 0 and 14 (Wilcoxon signed-rank test, ∗P = .013).
